Defining the single logic

Before touching any geometry, the first real decision on Porosity was what should actually drive the façade. Height was the obvious starting point every building naturally separates ground-level privacy needs from upper-level daylight needs  so the core rule became: one number, a panel's position between 0 (ground) and 1 (top), run through one shared formula to produce an "openness" value. The goal from the start was to avoid designing 100+ panels individually and instead write one rule the computer could apply to every panel at once. Privacy and daylight were treated as refinements on top of that height-driven base, not separate systems of their own  keeping the whole façade legible as one logic rather than a patchwork of rules.
